FILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 788,681, dated May 2,1905.

Application filed July 25, 1904- Serial No. 218,013.

To all wtont it may concern:

Be it known that I, FRANK C. H. ST1-msnenenn, a citizen of the UnitedStates, residing at Chicago, in the county ot' Cook and State ot'Illinois, have invented new and useful lmprovements inFillingh/lachines, ot' which the following' is a specilication.

'.lhe object oi' this invention is to automatical] y center a receptacleto be lilled in proper relation to the filling-tube ot' the machine, sothat the filling-tube will be sure to enter the bottle withoutencountering' the edge of its mouth.

For convenience in explaining the invention I have shown it in theaccompanying' drawings in .connection with the means Afor raising' thebottle of the kind disclosed in my application Serial No. 185,112 andwith a lilling-valve mechanism ot the kind disclosed in my applicationSerial No. 185,161, both iiled December le, 1903; but it will beunderstood that the invention can be adapted for other i'illing-machinesin which the filling-tube enters the bottle.

In the drawings, Figure 1 is a sectional view showing the invention withas much of the general structure ot' the machine as is necessary tounderstand the operation ot' the invention. Fig. 2 is an enlargedsectional view oi' the lilling-valve and bottle-guide. Fig. 3 is anelevation ot' the parts shown in Fig. 2 on a smaller scale.

Referring to the drawings, 10 is a liquid,

tank or receptacle to which the filling-valve mechanism is connected,and 11 is a bottle supported on a rest 12, which is carried by thevertically-movable stem 13. The bottle is raised to operate the valve bya cam 14, which operates a crank-lever 15, connected by one or morelinkslG to the stem 13.

The filling-valve mechanism comprises a body 17, which has a centralbore 17', into the lower end of which the iilling-tube 18 is secured.Rods 19 carry the liquid-valve 20, and a head 21, slidable on thelilling-tube, is provided withV openings 19 to receive these rods.Springs 22 on the rods normally hold the liquid-valve against its seatat the upper end ol" the bore 17. The head 21 is provided with anenlarged bore 23, which communicates by a passage 23 with avalve-chamber 24, and an air-tube 25 projects into this chamber andcarries a check-valve 26, which will open to permit air to 'How into thebottle, while an opening' 27 in the air-tube (controlled by theset-screw 28) permits air to flow from the bottle through the tube intothe tank. The upper end oil the air-tube projects through the body 17and carries a valve 29 in the housing 3() within the tank, a tube 31beingconnected to the housing' and extending' above the level oi? theliquid in the tank.

The present invention consists oi' a guide slid ably arranged on thefilling-tube to center the bottle automatically, so that the tube willenter the bottle properly without encountering the edge of its mouth,which would be apt to result in breaking the bottle andinjuring'themechanism. Thisguide32isshown in its lowest position on thefilling-tube in Fig'. 1 and in its elevated position in Fig. 2, and itis iiared or bell-shaped at its lower end 33 and provided with a socket34 to receive the mouth ol the bottle, which is adapted to engage therubber seat 35. The upper end ot' the guide is reduced in size orcontracted to enter a socket 36 in the lower end of the head 21,`and theguide is provided with a bore 37 to receive the filling-tube and alsowith one or more passages 39 to permit air to pass 'from the bottle intothe passage formed by the bore 23 oi the head. A rubber gasket 21 may belocated in the socket 36. The head is prevented from slipping' oil' ofthe iilling-tube at its lower end by providing a stop of suitablecharacter, as by flaring or expanding the tube, as shown at 38.

With a centering-head of this character the operator may place thebottle rapidly on the rest without being particular to observe that themouth of the bottle is exactly alined with the iillingtube, because thebottle will on its upward movement lirst engage the guide, which oilerssuiiicient resistance by reason of its weight to the bottle to cause itto move into proper position to receive the iillingtube. The inner wallof the socket 3a of the guide is smooth, and the outer edge of the mouthof the bottle will slide easily and freely thereon into position. On thecontinued upward movement of the bottle the guide is finally moved intothe socket 36 of the head and the latter moved upward to first unseatthe air-valve 29 and then unseat the liquidvalve 20. Vhile the bottle isbeing lowered the guide will return to its position at the lower end ofthe filling-tube by gravity.

Vithout limiting myselt1 to the exact construction and arrangement ofparts herein shown and described, what I claim, and desire t0 secure byLetters Patent` isl. In a lilium-machine, the combination of aliquid-tank, a liquid-valve in the tank, a filling-tube, a head slidableon the iilling-tube and connected to said valve, a valved air connectionbetween the tank and the head, and a slidable guide normally suspendedon the lilling-tube at the lower end thereof1 to adjust the mouth of thebottle to receive the tube, said guide being provided with anair-passage to form a communication between the air connection in thehead and the bottle.

2. In a lling-machine, the combination of a liquid-tank, a liquid-valve,a filling-tube, a head slidable on-the filling-tube and connected tosaid valve, a valved air connection between the tank and the head, and aslidable guide normally suspended on the illing-tube at its lower endand provided with an air-passage to form a communication between the airconnection in the head and the bottle, said guide having' its upper endcontracted and said head being provided with a socket at its lower endto receive the contracted end of the guide.
